Thisinvention relates to automatic vhibricating valves and is animprovement over my application of the samev title, Serial Number151,553, filed November 29, 1926,v

' which will appear as the description pro-v ceeds, the inventionconsists of the novel construction, combination and arrangement of partshereinafter described and claimed.

' L2.,() These objects are accomplished by devices illustrated lin theaccompanying drawings,

wherein Figure 1 is a view in side elevation of the device; t

Fig. 2'is a view in end elevation of the same; v

Fig. 3`is a view in vertical section taken substantially on a brokenline 3, 3 of Fig. 2; Fig. 4 is a view in vertical section takenY on A510 a broken line 4, 4 of Fig. 1

Fig. 5 is a view in horizontal section taken on a broken line 5, 5 ofFig. 4; Fig. 6 is a detail perspective view of' the plug valve; n f

Fig. 7 is a view in vertical section of a modiied form; and 1 Fig. 8 isa vertical section of another modied form.

Referring to the drawings throughout .n.49 which like reference numeralsdesignate like parts, the numeral 5 indicates the valve casing as awhole that is providedr with -a boss 6 on one side and having aconically tapered f valve seat 7 passing through same and adaptif ed toreceive a conical plug valve 8. The intake end' of said valve seat isprovided with a reducer nut 9 having an inwardly tapered opening 10. Anintake elbow member 11 hasv its inner end tapered at 12 to fit withinsaid .29 tapered opening and a spring 13 may be interposed between theend of the plug valve and the inner end of the member 11 to hold sameagainst its tapered seat.

. The ,plug valve v8 is hollow as shown at 14 with its open end `incommunication with the intake 11'. A hole lthrough the wall of l saidplug valve is adapted to, register with a passage 16 extending through'the wall of the casing 5 to a point at the remote end of a reservoir'17 which serves vas a container for 60 the lubricant. A slot 1 8, at thesame time, registers'with outlet passage 19 extend# ing thrQlgh the baseof the casing 5. Said casing. is provided with an annular flange 20 thatis adapted to form a connection with a compressed air mine drilling,machine or the likeand same may be readilysecured thereto by means ofbolts passing lthrough, lugs 21 as will he rea'dilyunderstood. Saidflange may he threaded 'for' connection as shown lin v70 Fig. 8 ifdesired. ,i

` It will be understood that the hole 15 yis in communication with itspassage 16 and the slot 1 8 is in communication with its outlet ,19 atone and the saine time. Thus part of the air or steamv entering thehollow plug valve 8 from the supply pipe 11 will pass vthrough theoutlet passagev i'nto the drill or yothermachine and part of the air orsteam *will passinto the reservoir 17 thus causing 80 a pressuretherein.l A nozzle member 22 projects through a hole 23 inthe boss 6into the reservoir 1 7.

'Said nozzle is exteriorly provided with a handle 124" and has anannular groove 2 5 with 85 holes 26 that are adapted to register with apassage 27"that ,communioateswith a hole A28 thinighgtlie"plug valve 8.Said h ole communicateswithfthe outlet passage 19 and it Will thus beseen that the pressure in the reservoir will force the lubricant intothe machine or engine that is to be lubricated as clearlyshown inthedrawings. The reservoir may be filled through 'the' hole 23 by removingthe nozzle member 22.

The` plug valve 8 is manipulated by a handle v29 having indentations'3()in the'underside lof its hub portion thaty register with a pin 31 set inthe casing 5 and impelled by a spring 32. In the drawings said handle isY shown with the plug valve in the operative position with the pressuremedium passing freely through the apparatus. By shifting said handle tothe other indentations the valve may be shut off as will be understood.

As a means for passing water through the device'into thedrifll machineattached thereto I have provideda'supply pipe 33 connected with apassage 34 in communication with a flush pipe 35 installed in a column36 passing centrally throughy the reservoirv 17. A nut 37 having agroove38 in its end is adapted to register with the passage 34 andprovide means for controlling the water Supply Referring to Figs. 3 and6, I have provided Y a spiral groove 42 in the plug valve 8 one end ofwhich is adapted to register with the passage 16 when saidvalve is shutoff while the other end. registers with the outlet 19'for the purpose ofreleasing the pressurewithin the reservoir 17 if desired. n

vIn the modified form of apparatus shown in 3. A lubricating valvecomprising a casing having a reservoir therein, a hollow plug valvehaving a hole adapted to register with a passage to form a communicationwith the remote end of the reservoir, means for madischarge passage, anozzle member for the reservoir having a groove and holes arranged toregister witha passage and hole through the plug valve to form acommunication between the reservoir and discharge passage.

In witness whereof,'I hereunto subscribe my naine this 21st day ofDecember, A. D

, ADOLPH NELSON'.

Fig. 7 the construction is substantially the same as in the preferredform although the position of several details is somewhat shifted. Inthe form shownin Fig. 8 I have provided a piston 39 for the reservoir17.Y Said Y piston is provided with a shaft() projecting exteriorlyofthe reservoir and provided with graduations which rserve as Ya lgaugeto indicate the amount of lubricant within said reservoir. In this formI also provide a passagelll between the valve seat 7 and reservoir thatis adapted to register with the slot 18 when the plug valve Sis in thereverse position so the compressed air may be'diverted to lift thepiston whenthe reservoir is empty.

` Having thus described my invention what I claim and desire to secureby Letters Patent is: g

1. A lubricating valve comprising a casing having a reservoir therein, ahollow plug Y valve having a hole adapted to register with a passage incommunication with the re- .i

mote end of the reservoir, said plug kvalve having a slot arranged .tofregister ywith a discharge passage, a nozzle member for the reservoirhaving a groove and holes arranged ,j

to register with a passage and hole through the plug valve tofformlacommunication fromthe reservoir to the discharge passage.

2. A lubricating valve comprising avcasing l Q having `a reservoirtherein, a hollow plug valve having a hole adapted to register with Y,

a passage to form a communication'with the remote end of the reservoir,said plug valve ,having a slot arranged to register with a disso Y.
